Abstract
Apparatus including an aquarium tank formed of a floor and spaced side walls with the organization arranged interiorly of the aquarium adjacent to an upper water level of water within the aquarium. The apparatus includes a single or plurality of pump members to direct water through a housing including filtration portions thereon to direct the recycled and thusly cleaned water through output conduits arranged adjacent the side walls of the aquarium and to direct the thusly cleaned water through a circulation tube to direct the water at the water level surface to enhance aeration and minimize turbulence within the aquarium. The circulation tube in a modified embodiment is formed of a transparent material including an array of parallel fiber optic cables to effect illumination and coloration of the recirculated water for an enhanced visual effect.
